STAMPING MACHINE AND DIE.

SPECIFICATION forming part of Letters Patent No. 268,041, dated November 28, 1882. Application filed August 7, 1882. (No model.)

To all whom it may concern: blocks being provided with dovetail projections Be it known that I, EDWIN- NORTON, of b, which slide in radial dovetail grooves b in Chicago, Cook county, State of Illinois, have the bed-plate B, the die-blocks being retracted invented certain new and useful Improvements by means of springs b when the hed-plate is 5 in Stamping Machines and Dies, of which the drawn back. The outer faces of the die-blocks following is a specification. Y b are out flaring or. wedgeshaped, and when Myinvention relates to improvements in dies thebed-plate' is raised they come in contact used in the manufacture of sheet-metal cans, with the bevel or conical surfaced cam ring or and more particularly to a die or machine for plate 0, which is bolted to the frame of the 10 making the coupling-indentations in the canmachine, thereby causing the die-blocks to cover, as shown in the can patented to me by move radially toward each other and clasp the Letters Patent No. 235,279, and hearing date can-cover. When the bed-plate is moved up December 7, 1880. the inner faces of the die-blocks form a perfect The present invention consists in a series of circle or solid ring around the can-cover and I5 movable dies mounted on a movable bed-plate, conform to its outer periphery.

By reference to said patent it will be seen that the seamless ring referred to is of much the same construction as a can-cover, with the bottom of the flat central portion thereof cut out.

It is obvious that my improvement may be used for other analogous purposes than that herein indicated.
